The synchronizer apparatus have a hub set on the shaft, a sleeve supported at the outside of the hub and engaged together, a sift gear with a clutch gear engageable with the sleeve, a synchronizer ring with friction surface, the lever members multiplying a force from the sleeve by using leverage and transmitting its multiplied force to the synchronizer ring. The lever members are disposed in a cut-off portions of the hub. Therefore, the apparatus become compact, eliminating a space for setting the lever members, and minimize the effect on a shift operation force, for the lever members are formed slmall to reduce the centrifugal force acting on them.
